re-install MSP 2007 server

We have re-installed MSP 2007 server in our development environment and want to copy the databases from our quality environment to prevent having to re-do all our custom settings. However, we receive unknown error messages when trying to publish projects from the client to the project web access server in the development environment.
So far we copied the following databases after a complete re-installation of the project web server:
ProjectServer_Archive
ProjectServer_Draft
ProjectServer_Reporting
ProjectServer_Published
Before we copied these databases, everything worked fine in the development environment.
Does anyone know which databases to copy and how we should do that?

Thanks,
Pat.
